Fastener

Abstract

A fastener comprises a fixing frame, a sliding base as well as a sliding frame and a swinging arm disposed inside the sliding base. A beveled guide surface of a fastening hook of a fastening rod of the fixing frame is pressed against a front side wall of the sliding base for inserting the fastening hook into a fastening groove in order that the sliding frame is fixed by the fastening rod at a fastening position. When the sliding base moves along a detaching direction from the fastening position, a turning portion of the swinging arm can be turned by pressing against an actuating rod, and a pressing portion of the swinging arm is driven by the turning portion to push the fastening rod upward for unfastening the sliding frame.

What is claimed is: 
     
         1 . A fastener, comprising:
 a fixing frame comprising a fastening rod pivotally disposed on the fixing frame, a fastening hook being disposed at an end of the fastening rod and a beveled vide surface being disposed along a side of the fastening hook;   a sliding base, a sliding frame being disposed inside the sliding base, a fastening groove being disposed on a front side of the sliding frame for the beveled guide surface of the fastening rod to press against a front side wall of the sliding frame for inserting the fastening hook into the fastening groove and fixing the sliding frame at a fastening position by the fastening rod; and   a swinging arm pivotally disposed on the sliding frame inside the sliding base, a pressing portion and a turning portion being disposed on the swinging arm, the pressing portion being actuated by the turning portion to turn, thereby, when the sliding frame moving along a detaching direction from the fastening position, the turning portion of the swinging arm being turned by pressing against an actuating rod, and the pressing portion being driven by the turning portion to push the fastening rod upward for unfastening the sliding frame.   
     
     
         2 . The fastener as claimed in  claim 1 , wherein the fastening hook has a fastening surface, and a fastening side is disposed inside the fastening groove for fastening with the fastening surface. 
     
     
         3 . The fastener as claimed in  claim 1 , wherein the actuating rod is disposed on the fixing frame and is extended passing an outer side of the fastening hook of the fastening rod. 
     
     
         4 . The fastener as claimed in  claim 1 , wherein the swinging arm is an L-shaped structure, and the pressing portion and the turning portion are disposed at two ends of the L-shaped structure respectively. 
     
     
         5 . The fastener as claimed in  claim 1 , wherein the swinging arm has a shaft for pivotally connecting the sliding frame, and the shaft is disposed at a position behind a back side of the fastening groove. 
     
     
         6 . The fastener as claimed in  claim 1 , wherein the fixing frame is disposed on a connecting frame in order that another end of the fastening rod is pressed against on the connecting frame.
